SPECIFICATION forming part of Letters Patent No. 380,023, dated March 27,1888. Application filed December 5, 188%. Serial No. 257,00l. (No model.)

. To all whomit may concern.-

Be it known that I, MICHAEL P. COLEMAN, of Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Lubricators, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- 1 Figure 1 is a side elevation of my improved lubricator; and Fig. 2, a front elevation, representing it in use. 1

Like letters and figures of reference indicate corresponding parts in both figures of the drawings. I

My invention relates to that class of lubricators which are employed in lubricating the ways of elevator-carriages; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective and otherwise desirable device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the carriage,

i in the well 0. There are usually four of these Ways, one at each corner of the carriage; but it is not deemed essential to show but two on the walls of the well in order to illustrate my invention. A lubricator is provided for each of the ways in the elevator-well, whether one or more are employed; but as they are all substantially alike in their construction and mode of operation I will describe but one.

Secured to the bottom D of the carriage A, adjacent to the way B, there is a bracket, E, and pivoted at w in said bracket there is a bellcrank lever, H. One of the arms, m, of said lever is arranged horizontally and at its outer or free end with a counterbalancing-weight, f, the other arm, 15, being arranged vertically and bent or curved inwardly at its outer or free end, as shown at v. Jointed to the lower end of the arm t by the link r there is a verticallyarranged lever, b, the upper end of which is bent or curved outwardly, as shown at z, and rests against the correspondingly-curved end I: of the arm 15. The link 1' is pivoted near the edges of thearm t and lever 12 opposite the curved ends '0 z, the connected parts at this point forming a knuckle or rule joint. Journaled in the lower end of the lever b there is a wheel, J, which may be covered with felt or any other suitable absorbent material.

Secured to the wall of the well 0, around or near the way B and below the lowest point to which the carriage A descends, there is a cup, K, partially filledwith oil, to, (said cup being shown in section in Fig. 1,) and so arranged with respect to the lever b that when said carriage is at the lower end of its route in the well the wheel J on said lever will be immersed or partially immersed in the oil in said cup.

From the foregoing it will be obvious that when the carriage descends the wheel J will enter the cup K and its felt covering become saturated with oil, and that as the carriage traverses the well said wheel will be kept constantlyin contact with the wayB by the weight f, thus lubricating it in a manner which will be readily apparent without a more explicit description.

In case the carriage accidentally descends at any time below the lower end of its route and the wheel J strikes the bottom of the cup K, the joint between said lever and the arm twill yield or be bent outwardly, as shown by the dotted lines in Fig. 1, thereby preventing injury to the cup and other parts of the lubricating apparatus.

The wheel J constitutes a dabber for removing the oil from the cup and applying it to the way; but a pad or dabber of any other suitable form and material may be employed instead of the wheel, although I deem a felt wheel preferable.

In some elevators there is but i one way or track for the carriage, consisting of a rod, tube, or post at the center, around which the carriage is built, and in others two or more are employed on the outer side of the carriage; but it will be obvious that my improved lubricator is equally well adapted for any elevator, whether one or more ways are used.

Having thus explained my invention, what I claim is- Ico 1. In a device for lubricating the ways of I elevator-carriages, the combination of the following instrumentalities, to wit: a carriage, a lever pivotally connected to the carriage and provided with a dabber, a counterbalancingweight for forcing the dabber against the way of the carriage, and an oil cup or receptacle for containing the lubricant, said receptacle being disposed on or adjacent to the way in such position that the dabber will enter the same, take up a portion of the lubricant and apply it to the way as the carriage performs its journeys downward and upward over the same, substantially as described.

2. In a device for lubricating the ways of elevator-carriages, the combination of the followinginstruinentalities, to wit: the bell-crank lever H, pivotally connected to the carriage A and providedwith the counterbalancing'weight f, the lever b, jointed to the 'arm t of said lever and provided with the wheel J, and the cup K, arranged to operate substantially as set forth.

3. In a device for lubricating the ways of elevator-carriages, the combination of the following instrumentalities, to wit: the pivoted lever H, having the arm t, provided with the curved end 12, the lever b, provided with the curved end 2, and wheel J, the curved ends of said lever and arm being jointed by the link r, substantially as described.
